Went on the Dyno today, basic 5.7L

Dang that's pretty smart, how long of a time-frame are we talking about with that progressive power return? Does it just cut ignition and/or fuel, since you said the air never slows down?

I'd have to dig into it for the number, but it's seamless. My clutch input switch is also at the top of the pedal's travel, so spark doesn't reengage until the clutch pedal is fully released.

It cuts fuel and retards spark.
